Elabela(19-32)
Based on 6 publication(s) in Google Scholar
Elabela(19-32) is an active fragment of ELABELA (ELA) that binds to apelin receptor (APJ). Elabela(19-32) activates the Gαi1 and β-arrestin-2 signaling pathways with EC50s of 8.6 nM and 166 nM. Elabela(19-32) induces receptor internalization and reduces arterial pressure, exerts positive inotropic effects on the heart.

Biological Activity
IC50: 8.6 nM (Gαi1) and 166 nM (β-arrestin-2)[1]
Elabela(19-32) (analogue 3) has a Ki of 0.93 nM for binding of radioligand apelin-13[Glp65, Nle75, Tyr77][125I][1].
Elabela(19-32) has an EC50 of 36 nM in HEK293 cells transiently expressing the HA-hAPJ receptor. Elabela(19-32) is slightly less potent than apelin-13 and ELA to elicit receptor internalization[1].
Elabela(19-32) (0.001 to 0.3 nM) has an EC50 of 1.5 pM in inducing changes in left ventricular developed pressure (LVDP) on the Langendorff perfused isolated rat heart[1].
